A系列
A系列使用新开发的非挥发性记忆体(Non-volatile memory - NVM)，使在增强读写表现的同时提供更佳的性价比。
全线A系列芯片不使用硬掩膜，用户可在最後一刻才把COS下载到芯片上。使用上更灵活，存货易於管理。
A系列产品亦内置记忆体管理单元(MMU)，加上防火墙的功能，使得这系列产品特别适合一卡多用的情况，确保芯片上各个应用能使用的资源得妥善的管理而不失安全性。
A系列带来以下便利：
使用新的NVM提高性价比
灵活 - 客户可以按照具体的需要将NVM划分为代码区和数据区
缩短生产周期 - 无需硬掩膜
高速处理可节省个人化时间
低功耗 - 更长的电池寿命
内置记忆体管理和防火墙 - 支持总管和用户模式，方便多一卡多用
安全功能 - 可将未经授权访问卡内数据的风险降到最低
uT83SCA1XY
SmartCard MCU with 100-160KB FLASH and High Speed I/O
The uT83SCA1XY is a contact mode smart card MCU, which complies with ISO7816 standard. It is targetting for high end GSM SIM Card applications and smart card applications require a large NVM.
uT83SCA1XY is a member of the A-series family, which is using advance NVM technology to meet customers’ need. It has an internal NVM that can be user configurable into program and data storage areas. The NVM area configured for user program
can be protected from accidental changes, making it similar to a typical mask ROM. The buit-in Memory Management Unit (MMU) together with firewall feature makes uT83SCA1XY suitable for multi-application environment.
Built-in memory size of each device are listed in table below:
Part No. NVM RAM
XY=60 uT83SCA160 160KB 4KB
XY=48 uT83SCA148 148KB 3KB
XY=30 uT83SCA130 130KB 3KB
XY=20 uT83SCA120 120KB 3KB
XY=00 uT83SCA100 100KB 3KB
